It covers models T8321-M and the SpaceView Pro Video Baby Monitor 720P. When the original cell degrades, the parent unit drops off charge fast or won't stay on at all.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpaceView Pro parent unit fit:\u003c\/strong\u003e\n    The T8321-M parent unit runs a 3.7V single-cell architecture. All SpaceView Pro variants in this line share the same cell format, connector pinout, and PCM board spec — which is why one cell covers the full model range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the SpaceView Pro parent unit. The onboard PCM handled charge cutoff cleanly at 4.2V and tripped undervoltage protection at the correct low-cell threshold without lockout issues.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eRe-pair after install:\u003c\/strong\u003e\n    Replacing the battery cuts all power to the parent unit. The SpaceView Pro loses its wireless link to the camera unit when power drops to zero — go into the parent unit menu after charging and re-pair with the camera before first use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SpaceView Pro parent unit drains overnight with the screen on\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe parent unit display running through the night is a sustained draw — backlit LCD plus active 2.4GHz radio plus IR receiver all pulling from a single cell simultaneously. At that combined load, even a healthy 5200mAh cell will read low by morning. The SpaceView Pro has a screen timeout setting in the display menu — set it to the shortest interval you can tolerate. That alone cuts overnight draw significantly without affecting audio alerts.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eParent unit shows \"out of range\" immediately after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA freshly installed cell often ships at partial charge — typically around 3.6V. The SpaceView Pro's 2.4GHz radio module is voltage-sensitive; at low cell voltage, transmit power drops and the parent unit reports poor or no signal even when physically close to the camera. Charge the parent unit to full before testing range. A full charge brings the cell to 4.2V, which restores full radio output. If range is still reduced after a complete charge cycle, perform a fresh camera-to-parent-unit pairing from the menu.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43315064143962,"sku":"BWCS-EFT832MB-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43315064176730,"sku":"BWCS-EFT832MB-2","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43315064209498,"sku":"BWCS-EFT832MB-3","price":37.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EFT832MB-1.webp?v=1777949547","url":"https:\/\/batteryweb.com\/products\/eufy-spaceview-pro-baby-cam-replacement-battery-37v-5200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
